Introduction
In the last year of High school it is necessary to learn about the production of ethanol. It is a rather simple process but by watching an informative video it is possible to understand it much better.
Task
For this task you will need to watch a short video about the making of ethanol and after that you will have to answer 10 questions which are based on the video. Good luck!
Process
1. What is the main ingredient for making ethanol in this video?
2. What is the first the first step in the process of making ethanol?
3. What needs to be added to the corn flour and water mixture to break starch into simple sugars?
4. What needs to be added to cold mash to enter it in the fermentation process?
5. What is the next step of making 190-proof ethanol?
6. What is used to further dehydrate water from ethanol?
7. What kind of technology is used to separate the leftover mash from solids?
8. What can be made by condensing this filtered mash?
9. Why it is easy to separate corn oil from this product?
10. What is the alcohol content of the mash and yeast product after the fermentation process?
Now pass on to the next page to evaluate your score.
Evaluation
1. Corn
2. Milling the corn
3. Enzymes
4. Yeast or yeast and enzymes
5. Distillation
6. Sieve bieds
7. Centrifuge
8. Syrup
9. Because oil is much lighter
10. 12 - 14%
If you have got 8 to 10 correct answers, you are doing great! Congratulations!
If you have got 5 to 7 correct answers, you are doing great but you could have listened a bit more carefully to the video material.
If you have got 0 to 4 correct answers, you have to watch the video again and try to answer the questions a second time.
Conclusion
You have accomplished the test and hopefully learned something more about this process!
I hope this gave you a little more insight on the production of ethanol which is commonly used in our daily life.
Thank you for your participation!
Have a great day!
